This study considers a monopolist remanufacturing enterprise under both mandatory carbon emission capacity and take-back regulations. We explore the optimal decisions of the remanufacturer and investigate the impacts of regulations on both the economy and environment. Using stylized models, we study four scenarios (i.e., with and without take-back and carbon emission capacity regulations). We first analyze how should the remanufacturer adjust operational decisions to maximize profit. We then explore both the economic and environmental implications of regulations. Our analysis reveals: (1) Carbon regulation is not only an effective way to reduce carbon emissions but can also stimulate remanufacturing. (2) For the enterprise, both take-back and carbon emission capacity regulations lead to lower profit, and we provide guidance for the enterprise to make production and pricing adjustments. (3) For the government, carbon cap is an effective measure to reduce the environmental impact; however, when setting the remanufacturing target, it is critical to evaluate the environmental impact during disposal phase.

本研究考虑了强制性碳排放量和回收法规下的垄断者再制造企业。我们探索再制造商的最佳决策，并研究法规对经济和环境的影响。使用程式化模型，我们研究了四种方案（即，有无回收和碳排放能力法规）。我们首先分析再制造商应如何调整运营决策以实现最大利润。然后，我们探讨法规的经济和环境影响。我们的分析表明：（1）碳监管不仅是减少碳排放的有效方法，而且还可以刺激再制造。（2）对于企业而言，回收和碳排放能力法规均导致利润降低，并且为企业进行生产和价格调整提供指导。（3）对于政府而言，碳封顶是减少环境影响的有效措施；但是，在设定再制造目标时，评估处置阶段的环境影响至关重要。
